On the estimation of nuclear level density parameters in the region of some large deformed nuclei

Calculation of Nuclear Level Density Parameters of Some Light Deformed Medical Radionuclides Using Collective Excitation Modes of Observed Nuclear Spectra

“…Now, we can compare the observable level densities in Eqs. (6) and (12) which have similar dependence on the energy, even though they have been obtained from different approaches. Equation (6) obtained from Bethe theory has been based on a single-particle nuclear model whereas Eq.…”

“…[1][2][3][4][5][6][7][8][9][10] In particular, level densities have been used successfully in estimation of the neutron-capture cross section basic data, required for both design and nuclear model calculations in nuclear science and technologies. At present, the knowledge of these cross section basic data obtained from nuclear level density approaches has been useful in studying the several applied fields; e.g.…”

“…Recently in considerable studies such as in [6][7][8][9][10][11][12], it has been attempted to identify the nuclear level density parameters in the region of some light and large deformed nuclei by the use of a simple model of nuclear collective excitation mechanism. Almost all data on the estimated level density parameters of these deformed nuclei are well identified on a base of collective rotational and collective vibrational bands such as ground state band, β band, octupole band, γ-band, and so forth.…”

“…The knowledge of nuclear level densities is a crucial input in various fields/applications such as the creation of consistent theoretical description of excited nucleus properties and the nuclear reaction cross-section calculations for many branches of nuclear physics, nuclear astrophysics, nuclear medicine, and applied areas (medical physics, etc.) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The neutron capture cross-sections, required for both design and nuclear model calculations in nuclear science and technologies, are approximately proportional to the corresponding level densities around the neutron resonance region.…”

“…And, it is well known that nuclear level density parameters are of crucial importance for the cross-section. In light of the preceding knowledge in the present study, the nuclear level density parameters of deformed 203−209 Pb and 206−210 Bi target isotopes used on the ADS systems have been calculated by using different collective excitation modes of the observed nuclear spectra near the neutron binding energy and a simple model introduced in our previous works [6][7][8][9][10][11][12], in which the collective character of the nuclear excitations is available.…”
